DBS-C01 Management and Operations Practice Question
Exhibit
Resource: "arn:aws:rds:us-east-1:123456789012:db:mydb"
Action: "rds:CreateDBSnapshot"
Effect: Allow
Condition: {
"StringEquals": {
"aws:RequestedRegion": "us-east-1"
}
}Refer to the exhibit. An IAM policy statement allows creating manual snapshots for an RDS instance. A database administrator is unable to create a snapshot from the AWS Management Console. The error message indicates insufficient permissions. What is the likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The policy does not include necessary read actions (e.g., 'DescribeDBInstances', 'DescribeDBSnapshots') that the console uses.
The AWS Management Console often performs multiple API calls (such as DescribeDBInstances and DescribeDBSnapshots) to list and display resources before allowing actions. Even if the CreateDBSnapshot action is allowed, the console will fail if it cannot describe the instance or snapshots. Option A is incorrect because the condition key 'aws:RequestedRegion' is correctly spelled. Option C is incorrect because the resource ARN correctly identifies the RDS instance for snapshot creation. Option D is incorrect because StringEquals is appropriate for matching the region exactly; StringLike is not needed.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The condition key 'aws:RequestedRegion' is misspelled.
Why it's wrong here
The condition key is correctly spelled.
- ✓
The policy does not include necessary read actions (e.g., 'DescribeDBInstances', 'DescribeDBSnapshots') that the console uses.
Why this is correct
The console requires read permissions to list instances and snapshots before creating a snapshot.
- ✗
The resource ARN is incorrect; it should include the snapshot ARN.
Why it's wrong here
For creating a snapshot, the resource is the DB instance, not the snapshot.
- ✗
The condition uses 'StringEquals' but should use 'StringLike' for region matching.
Why it's wrong here
StringEquals is appropriate for exact region matching.
